The first thing you need to do if you think your Facebook account has been compromised is to change your password. Then, if you use Facebook to log in to apps like Spotify or Instagram change your logins too. This will prevent the hacker from accessing the third-party apps through your compromised Facebook profile.
A compromised Facebook account can offer hackers access to a wealth of personal information. Hackers could use this information for malicious reasons, like taking credit card numbers and bombarding people with fake credit card offers or frauds involving phishing. They could also use the hacked account to send threatening messages to friends, or even post on your timeline with your name (as if you did it yourself).
One of the most frequent ways hackers get into an account is when they exploit an error in Facebook’s application code. A flaw in the iOS Facebook app allows hackers to take over cookies, and steal the “access token” of an iPhone user. These tokens, which are digital keys, give them full control over the user’s Facebook Account, as well as any other website they sign into using their Facebook credentials.
A hacker can also gain access to a user’s account by using brute force attacks. This method involves figuring out passwords, usually the most commonly used ones like 123456789 and 1234567890. In addition, hackers could gain access to accounts by sifting through compromised credentials. There are several free tools that can be used to check for stolen data, including a popular site called HaveIBeenPwned.
